“…Spectral interference from emission-rich matrix elements on the determination of analytes at trace level is one of the major problems faced by researchers (6)(7)(8)(9)(10). To suppress the spectral interference, the emission-rich matrix element is preferentially separated from the trace analytes either physically using the d.c. arc carrier distillation technique utilizing the differences in the volatilization characteristics (11)(12)(13)(14), or chemically by selective extraction of the emission-rich matrix element from analytes using a suitable ligand system followed by analysis of the raffinate (15)(16)(17)(18)(19)(20)(21). Even though the d.c. arc technique is advantageous due to its simplicity, requiring less sample handling and less time, it suffers from poor precision due to arc wandering (22)(23).…”

“…The uncertainties associated with trace metallic determination of platinum by EDXRF has been discussed by Remya Devi et al [22]. Radiochemistry Division at Bhabha Atomic Research Centre (BARC) is engaged in the quality control programme of various nuclear materials primarily by atomic spectroscopic techniques from trace metallic point of view for the last few decades [23,24]. However, for major, minor and some of the trace elemental analyses, EDXRF based technique have been developed and being routinely used.…”

The applicability of energy dispersive X-ray fluorescence spectrometry as an analytical technique for the determination of a few metallic impurities such as Ca, Cr, Cu, Fe, Mn, Pb, and Zn in alumina (Al 2 O 3 ) matrix was investigated. A series of Al 2 O 3 standards containing the elements of interest in the range 10-1000 ppm was prepared and the spectrometer conditions were optimized to obtain calibration plots for the various analytes that could be further used for the analysis of actual samples. The present method serves as an alternative to currently used AES method for analytes expected in the concentration range 50-1000 ppm.

“…The atomic emission spectroscopy (AES) technique, being simultaneously multi-elemental and having acceptable analytical performance (detection limits, sensitivity, linear dynamic range, etc. ), is regularly used for the determination of trace metallic analytes in nuclear fuels and associated materials (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17). Zirconium (Zr) is accepted worldwide as a cladding material in the nuclear industry due to its low neutron absorption cross-section.…”

Chemical (ICP-AES) or physical (d.c. arc carrier distillation technique) separation of the major matrix, followed by the determination of trace metallic impurities in the raffinate, is a well accepted protocol in the nuclear industries to avoid spectral interferences from emissionrich matrices such as U, Pu, Zr, Th, etc. With ICP-AES analysis, the RSD is better (less than 5%), separation is time-consuming, involves handling of the materials which increases the chances of contamination, while the precision of the d.c. arc technique is 15-25%. Thus, there is a need to have an ICP-AES-based methodology where the analytes can be determined in a nuclear matrix at trace levels without requiring chemical separation. In this paper, an attempt was made to develop a method for the determination of trace constituents in a Zr matrix without separation by using the flexibility of a charge coupled device (CCD) detector for choosing additional interference-free analytical lines for Mn,
